SWITCH-OPERATING MECHANISM.

Specification of Letters Patent. Patented J u'ne 14, 1921.

' Application filed August 2, 1919. Serial No. 314,998.

To all whom z'tmay concern:

Be it known that I, CHARLES MAKoBEn, a citizen of the United States, residing at Stockton, in the county of Muscatlne and State of Iowa, have invented new and useful Improvements in Switch-Operating Mechanism, of which thefollowing is a speclfica- This invention relates to a mechanism by means of which a switch may be operated from a remote pointand has for its primary object to provide a mechanism of simple construction in which the time of operation of the switch may be accurately controlled under existing conditions. 3

An object of the invention is to provide simple means for holdin the switch blade in open and closed position dependingem tirely upon what position the switch has been forced by the mechanism.

Besides above my invention is distinguished in the construction and arrangement of parts so that a float in the movement thereof may accurately control the amount of water or liquid passing through areceptacle;

With theseand other objects in-view the invention will be better understood from the following detailed description if taken in connection with the accompanying drawings, wherein Figure 1 is side-elevation of the invention showing the switch in operation.

Fig. 2 is a plan view'of a portion of the device, i

Fig. 3'is an enlarged side elevation of a portion,

Fig. 4 is a front elevation of the switch, Fig. 5 is a detail section of the sliding connection,

Fig. 6 is an enlarged view of the bell crank lever and o crating member, and.

Fig. 7 is a detail section through the opcrating member.

Referring to the drawing the numeral 1 designates a' switch which may be of any suitable construction or type now on the market. The movable member of the switch 1 has connection with a link 2 which in turn has a pin and slot connection with a second of its two link 3. This second link 3 has pivotal connectlon 4 with one arm 5 of a bell crank lever 6. The remaining arm 7 of this bell crank lever has projecting laterally therefrom a pin 8 which may be in the form of a bolt screwed into the limb and this pin 8' is slidably re ceived in a slot 9 formed in the upper end portion of a stem 10, the lower end portion of which is fixed to a float 11. The pivot 12 of the bell crank lever is so disposed with relation to a tractile spring 13 that this single spring will snap the bell crank lever to either positions with the advantage that the switch will be forced to or closed position-depending entirely upon the position of the float.

connection with the accompanying drawing it will be seen that upon the rising and fall of. the liquid within the receptacle B the float will be raised and lowered and through its pin and slot connection with the bell crank lever, the same will be thrown about its pivot for shifting the links which in their movement will open and close the switch. When this action has taken place the spring will be shifted to either one side or the other of the pivot of the bell crank thereby snapp'ingthe parts tions. As my invention may be used for a variety'of purposes-I consider it advisable to show means for allowing an adjustable connection between the float stem and the bellcrank lever so-vthat different levels of liquid can be accommodated. One manner of accomplishing this is shown in Fig. 6 as consisting of collars 15 and 1 6 encircling the stem adjacent the slot and rigidly held in an adjusted position by screws 17. Thus it wi I be seen t' each other the length of the slot may be reduced and vice versa when the collars are moved away from each other. By this coneither in an open to their final adjusted posiat by moving the collars towardstruction it will be seen that the distance of travel of the float stem before actuating the mechanism may be changed at will. It is of Y 65 From the foregoing descriptiontaken in other relations and therefore I do not desire bell crank lever having a slot and pin con- 10 0 be limited in any manner except as set orth in the claim hereto appended. What I claim is Means .for throwing a switch including a movable blade, comprising a link connected with the blade, a hinged leaf at one end of said link formed with a slot, a second link carrying a pin passing through said slot, a

nection with said second named link, a spring for holding said named lever past center at either limit of its movement, and a rod carrying a float and having a lost motion connection with said lever. I

In testimony whereof I affix my signature.

CHARLIE MAKOBEN.
